Abstract

The embodiment of the invention provides a display screen and electronic equipment, relates to the technical field of display, and can perform effective electrostatic protection on transistors in a display panel. The display screen comprises a display panel, and the display panel comprises a display area and a non-display area surrounding the display area; the non-display area is provided with an electrostatic discharge structure, the electrostatic discharge structure is located in the edge area of a layer above the substrate of the non-display area, the outer edge of the electrostatic discharge structure is flush with the cutting edge of the substrate of the display panel, and the electrostatic discharge structure is electrically connected with a constant voltage structure used for providing fixed voltage.

Description

technical field [0001] The present application relates to the field of display technology, and more particularly to a display screen and an electronic device. Background technique [0002] In the daily use of electronic devices such as mobile phones, the screen of the electronic device will often rub against fingers or clothing, thereby accumulating triboelectric charges on the surface of the screen. When the triboelectric charge caused by friction accumulates to a certain extent, the triboelectric voltage accumulated on the surface of the screen may reach negative hundreds of volts or even negative one thousand volts. At this time, the triboelectric charge will be conducted and induced towards the substrate of the display panel. An electric field is formed at the bottom of the panel. The electric field will cause the characteristics of the transistors in the display panel to drift, which increases the leakage current of the transistors, thereby causing the display panel to...
